System and method for protecting payload information in radio transmission

Abstract

System and method for improving the protecting radio channels in transmission, according to which the payload information of the signal to be transmitted is divided into a plurality of data portions of smaller size which are then grouped into packets and the packets are labeled based on a criterion from among a plurality of criteria, said criterion being indicative of a level of priority associated to said packets. The packets are subsequently radio transmitted in accordance with their level of priority indicated by their associated label.

1. A method of protecting payload information in radio transmission comprising the steps of:
 dividing a payload into a plurality of data portions, 
 identifying data portions according to a criterion of protection, 
 grouping data portions identified as having the same criterion in a packet, 
 labeling said packet containing data portions with the same criterion, said labeling being indicative of a protection priority level for the packet, and 
 incorporating at least one packet in a selected radio channel such that packets are incorporated in the selected channel according to said protection priority level. 
 
     
     
       2. A method according to  claim 1  wherein in case a channel for transmitting a data portion becomes faulty, the data portion is transmitted using another channel having available capacity. 
     
     
       3. A method according to  claim 1 , wherein the criterion of protection is based on the type of information and/or the nature of communication. 
     
     
       4. A packet processing unit for protected radio transmission of a payload information the packet processing unit configured for:
 dividing a payload into a plurality of data portions, 
 identifying data portions according to a criterion of protection selected from a plurality of criteria of protection, 
 grouping data portions identified as having the same criterion in a packet, and 
 labeling said packet containing data portions with the same criterion said labeling being indicative of a protection priority level for the packet. 
 
     
     
       5. A packet processing unit according to  claim 4  comprising a packet builder for adding a header to said packet. 
     
     
       6. A packet processing unit according to  claim 5  wherein the packet builder is adapted for labeling said packet containing data portions with the same criterion said labeling being indicative of a protection priority level for the packet. 
     
     
       7. A transmitter for protected radio transmission of a payload information comprising a packet processing unit for protected radio transmission of a payload information the packet processing unit configured for:
 dividing a payload into a plurality of data portions, 
 identifying data portions according to a criterion of protection selected from a plurality of criteria of protection, 
 grouping data portions identified as having the same criterion in a packet, and 
 labeling said packet containing data portions with the same criterion said labeling being indicative of a protection priority level for the packet. 
 
     
     
       8. A transmitter according to  claim 7  further comprising:
 a packet aggregator for multiplexing a plurality of packets formed by said packet processor to form a multiplexed packet stream, 
 a packet allocator for allocating at least one packet from said multiplexed packet stream to one or more available radio channels wherein packets are incorporated in the channel according to said protection priority level, 
 a radio transmitter module for radio transmitting said available radio channel with said packet allocated to said radio channel. 
 
     
     
       9. A programmable device comprising storage means with a software program recorded thereon, the software program comprising instructions which, when executed on the device, cause the device to carry out the steps of:
 dividing a payload into a plurality of data portions, 
 identifying data portions according to a criterion of protection, 
 grouping data portions identified as having the same criterion in a packet, 
 labeling said packet containing data portions with the same criterion, said labeling being indicative of a protection priority level for the packet, and 
 incorporating at least one packet in a selected radio channel such that packets are incorporated in the selected channel according to said protection priority level.
